Description

Technical Field

[0001] This utility model relates to the field of trampoline technology, specifically to a children's handrail trampoline. Background Technology

[0002] A trampoline is a tool used to provide recreational activities. It generally consists of a basic frame and a jumping cloth arranged on the frame. Multiple springs are arranged between the jumping cloth and the frame, which can provide additional elasticity when the user jumps on the jumping cloth.

[0003] Chinese patent number CN202420169867.9 discloses a trampoline with handrails. By rotating the positioning pin, the inner end of the handrail extends into the second mounting hole, thereby positioning the inner tube on the outer tube and realizing the extension and retraction of the handrail.

[0004] The applicant discovered the following technical problems when implementing the above-mentioned technical solution:

[0005] The above adjustment method requires several mounting holes for positioning pins. Adjusting the handrail requires laborious searching and aligning the mounting holes with the positioning pins, making it very inconvenient to use. Since children's height changes rapidly, frequent adjustments are necessary, otherwise it may lead to poor posture in children. Secondly, the handrail can only be adjusted according to a few preset fixed positions, and cannot be precisely set to the required size to accurately suit users of different heights, which may affect children's development and lead to poor posture in children.

[0006] Therefore, providing a children's handrail trampoline with stepless adjustment to precisely set the handrails at the required height is a problem that this utility model urgently needs to solve. Utility Model Content

[0007] To address the aforementioned technical problems, the purpose of this utility model is to overcome the limitations of existing technologies where the armrest's telescopic adjustment requires several mounting holes for positioning pins. This necessitates laborious searching and alignment of the mounting holes with the positioning pins, making it inconvenient to use. Furthermore, children's height changes rapidly, requiring frequent adjustments, which can lead to poor posture. Additionally, the existing armrests can only be adjusted to a few preset fixed positions, failing to precisely set the required size to suit users of different heights, thus affecting children's development and potentially causing poor posture. Therefore, this utility model provides a children's handrail trampoline that allows for stepless adjustment to precisely set the armrest to the desired height.

[0008] To achieve the above objectives, this utility model provides a children's handrail trampoline, which includes: a main frame, an outer tube, an inner tube, a locking block, and a rotating column. The outer tube is vertically arranged on one side of the main frame. A limiting block is provided on the inner wall of the outer tube along its axial direction. A limiting groove adapted to the limiting block is recessed on the outer wall of the inner tube and is coaxially and telescopically assembled inside the outer tube. A mounting frame is provided at the upper opening of the outer tube. The locking block is reciprocally disposed inside the mounting frame and can move towards the limiting groove. The rotating column is rotatably disposed on the mounting frame off its axis and can drive the locking block to move towards the limiting groove.

[0009] Preferably, guide rods are provided on opposite sides of the locking block, and guide grooves adapted to each guide rod are provided on the inner wall of the mounting bracket.

[0010] Preferably, a lever is provided on one side of the rotating column.

[0011] Preferably, the inner tube is U-shaped, and the main frame is provided with limiting frames on opposite sides that are adapted to the outer tube.

[0012] Preferably, the main frame has several legs vertically arranged around its bottom, and each leg has a first suction cup at its lower end.

[0013] Preferably, a second suction cup is provided at the lower end of each outer tube.

[0014] Preferably, the limiting groove is provided with scale lines at intervals along its length.

[0015] According to the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows: First, by adjusting the height of the inner tube, the height of the entire armrest is adjusted to accurately adapt to the height of children. Then, the rotating column is rotated. Due to its design that is off-center from its axis, it can abut against the locking block when rotating and drive it to move towards the limiting groove, thereby applying pressure to the limiting groove and thus fixing the height of the inner tube. Since it is not necessary to find and align the mounting hole with the positioning pin, the installation process is simplified. Secondly, this adjustment method is stepless, which can freely set the height of the armrest without being limited by gears.

[0016] Other features and advantages of this utility model will be described in detail in the following detailed description section; and all parts not covered in this utility model are the same as or can be implemented using existing technology. Attached Figure Description

[0028] Reference Figures 1-5 A children's handrail trampoline includes: a main frame 1, an outer tube 2, an inner tube 3, a locking block 4, and a rotating column 5. The outer tube 2 is vertically arranged on one side of the main frame 1. A limiting block 201 is provided on the inner wall of the outer tube 2 along its axis. A limiting groove 301 adapted to the limiting block 201 is recessed on the outer wall of the inner tube 3 and is coaxially and telescopically assembled inside the outer tube 2. A mounting frame 202 is provided at the upper opening of the outer tube 2. The locking block 4 is reciprocally movable inside the mounting frame 202 toward the limiting groove 301. The rotating column 5 is rotatably mounted on the mounting frame 202 off its axis and can drive the locking block 4 to move toward the limiting groove 301.

[0029] This application first adjusts the height of the inner tube 3 to precisely accommodate a child's height, thereby adjusting the height of the entire armrest. Then, the rotating column 5 is rotated. Due to its off-center design, it can abut against the locking block 4 during rotation and drive it to move towards the limiting groove 301, thereby applying pressure to the limiting groove 301 and fixing the height of the inner tube 3. Since there is no need to find and align the mounting hole with the positioning pin, the installation process is simplified. Secondly, this adjustment method is stepless, allowing the armrest height to be freely set without being limited by gear positions.

[0030] Reference Figure 5 The locking block 4 is provided with guide rods 401 on both sides, and the inner wall of the mounting bracket 202 is provided with guide grooves 203 that are adapted to each guide rod 401.

[0031] The locking block 4 of this application can be stably and reciprocally moved in the guide groove 203 in the direction of the limiting groove 301 via the guide rod 401, and will not be misaligned.

[0032] Reference Figure 3A lever 501 is provided on one side of the rotating column 5.

[0033] The user of this application can use the lever 501 to rotate the rotating column 5, thereby driving the locking block 4 to move toward the limiting groove 301.

[0034] Reference Figure 2 The inner tube 3 is U-shaped, and the main frame 1 is provided with limiting frames 101 on opposite sides that are adapted to the outer tube 2.

[0035] The outer tube 2 is vertically inserted into the limiting frame 101. The two ends of the U-shaped inner tube 3 are retractably installed in the outer tube 2. The continuous U-shaped handrail provides children with a complete and continuous gripping surface. Whether gripping the middle crossbeam or the two side vertical tubes, it is a tightly integrated whole, and there is no sense of insecurity or risk of hand slippage when gripping different parts.

[0036] Reference Figure 2 The main frame 1 has several legs 102 arranged vertically around its bottom, and each leg 102 has a first suction cup 103 at its lower end.

[0037] This application uses a first suction cup 103 to adhere to the ground to prevent the trampoline from shifting or tipping over during use.

[0038] Reference Figure 3 Each outer tube 2 is equipped with a second suction cup 204 at its lower end.

[0039] This application uses a second suction cup 204 to adhere to the ground, in order to further prevent the trampoline from shifting or tipping over during use.

[0040] Reference Figure 3 The limiting groove 301 has scale lines spaced apart along its length.

[0041] Users of this application can precisely adjust the height of the armrests by observing the scale lines to suit the height of children.

[0042] When using the device provided by this utility model, the height of the entire armrest is first adjusted by adjusting the height of the inner tube 3 to accurately adapt to the child's height. Then, the rotating column 5 is rotated. Due to its off-center design, it can abut against the locking block 4 when rotating and drive it to move towards the limiting groove 301, thereby applying pressure to the limiting groove 301 and fixing the height of the inner tube 3. Since there is no need to find and align the mounting hole with the positioning pin, the installation process is simplified. Secondly, this adjustment method is stepless, which can freely set the height of the armrest without being limited by gears.

[0043] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0044] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0045] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
